We need some sort of identifier to check teh circumstances and to unban. Without a name we would need your Warband ID

If you do not other wise know your ID, you can get the Warband ID by joining a server and then asking an admin to let you know your ID. Some servers have mods that show such ID's automatically, so you could look for one of those servers, join it and write down the ID (you can press "L" for the log in case it disappears to quickly).
